Just installed 18.2 on Linux Mint and faced I can't add any SAMBA share with Zeroconf as File Exists error appears instead of login/password prompt.

Also no SAMBA shares visible when adding through Windows network (SMB).

NFS doesn't allow to enter particular share.

No such problems with 18.2 running on Windows or macOS.

The server I'm trying to acces is a Linux based QNAP one.

NFS should be relatively easy via a NAS like QNap.

Which SMB version is running on your NAS?

If I only knew ))
Looks like SMB1 to SMB3

Even if you can't browse the smb network, you can still add a network location by using "Add network location" at the bottom of the dialog and entering the relevant information in the next dialog.

The wiki says ;

Note: Network browsing is no longer possible with Samba v2 and upwards. Samba v1 was deprecated May 2018.

See section 3, step 5 https://kodi.wiki/view/Adding_video_sources for more details.

As you're running Linux on both your server and client, I'd just use NFS.

I'm not using Linux anymore. )
It takes too much effort to do the simpliest things.

Really ?  Example exports file on one of my machines that shares two drives via nfs over the network.

php:
/mnt/nas    192.168.1.1/24(rw,all_squash,insecure,no_subtree_check)    

/mnt/win    192.168.1.1/24(rw,all_squash,insecure,no_subtree_check)

Mounted locally on one of machines via fstab

php:
192.168.1.125:/mnt/nas    /media/nas-drive    nfs    rsize=8192,wsize=8192,timeo=14,intr

192.168.1.125:/mnt/win        /media/windrive        nfs    rsize=8192,wsize=8192,timeo=14,intr

Very simple, easily connectable to Kodi either via the local mount or browsing the nfs shares through kodi and faster than smb.  Still, do what works for you.
